LetsEncrypt comes with it's own built-in web server listener for just such a use case, so we can accomplish this! Since we want our SSL certificate on the load balancer (SSL Termination), our goal is to find a way to have HAProxy recognize a request from LetsEncrypt and route it to a web service that will respond with the response LetsEncrypt needs to authorize the certificate. Our application servers won't be able to handle this authorization request. It won't serve files by itself - it will only redirect a request to another location. The first hurdle to get around arises because LetsEncrypt authorizes a certificate for a server by requesting a file via an HTTP(S) request. However, since we have some unique needs with HAProxy, we'll use a slightly different CRON task for this use case. This default is very handy for a typical installation. Checking twice a day is a relatively safe way to check and get around potential timing bugs. The certificate only gets renewed if it's under 30 days from expiration. Here's how I install LetsEncrypt (Certbot) on Ubuntu 16.04: sudo add-apt-repository -y ppa:certbot/certbotДЄs the video shows, this installer creates a CRON task ( /etc/cron.d/certbot) to request a renewal twice a day. Let's get some boilerplate out of the way. Since we're using LetsEncrypt on a load balancer (HAProxy) which cannot serve the authorization HTTP requests that LetsEncrypt makes, we have some unique issues to get around. LetsEncrypt (certbot) is great for this, since we can get a free and trusted SSL certificate.

Part of what I wanted to cover was how to use SSL certificates with a HAProxy load balancer. This is a video from the Scaling Laravel course's Load Balancing module.
